Abstract (en)
[origin: EP4216632A1] Embodiments of this application provide a wireless communication method and a communication apparatus. The method includes: receiving an RRC message from an access device, where the RRC message includes SRS configuration information, the SRS configuration information indicates a plurality of SRS resources, and each of the plurality of SRS resources is sufficient for transmission of one SRS; sending an SRS to the access device based on the SRS configuration information and a preset scheduling policy by using a part of all transmit ports, so that a quantity of SRSs sent to the access device is less than a quantity of the plurality of SRS resources indicated by the SRS configuration information. In this way, a terminal reduces the quantity of sent SRSs, and triggers the access device to reduce a quantity of MIMO layers used for sending a PDSCH, and the terminal may receive data of the PDSCH by using fewer receive antennas. This helps reduce power consumption of the terminal and improve performance of the terminal.
